Reconciling fabric parameters individually

1. Log in to one of the segmented switches as admin.
2. Enter the configShow -pattern "fabric.ops" command.
3. Log in to another switch in the same fabric as admin.
4. Enter the configShow -pattern "fabric.ops" command.
5. Compare the two switch configurations line by line and look for differences. Do this by
6. Connect to the segmented switch after the discrepancy is identified.
7.
8. Enter the configure command to edit the appropriate fabric parameters for the segmented
9. Enable the switch by entering the switchEnable command.
Alternatively, you can reconcile fabric parameters by entering the configUpload command for each
switch and upload a known-good configuration file. If you do this option, the two switches will need
to be the same model.

Downloading a correct configuration

You can restore a segmented fabric by downloading a previously saved correct backup
configuration to the switch. Downloading in this manner reconciles any discrepancy in the fabric
parameters and allows the segmented switch to rejoin the main fabric. For details on uploading
and downloading configurations, see the Fabric OS Administrator's Guide.

Reconciling a domain ID conflict

If a domain ID conflict appears, the conflict is only reported at the point where the two fabrics are
physically connected. However, there may be several conflicting domain IDs, which appear as soon
as the initial conflict is resolved.
Typically, the fabric automatically resolves domain conflicts during fabric merges or builds unless
Insistent Domain ID (IDID) is configured. If IDID is enabled, switches that cannot be programmed
with a unique domain ID are segmented out. Check each switch that has IDID configured and make
sure their domain IDs are unique within the configuration.
Repeat the following procedure until all domain ID conflicts are resolved.
1. Enter the fabricShow command on a switch from one of the fabrics.
2. In a separate Telnet window, enter the fabricShow command on a switch from the second
3. Compare the fabricShow output from the two fabrics. Note the number of domain ID conflicts;

comparing the two Telnet windows or by printing the configShow -pattern "fabric.ops" output.
Also, verify that the fabric parameter settings (see the above list) are the same for both
switches.
Disable the switch by entering the switchDisable command.

there may be several duplicate domain IDs that must be changed. Determine which switches
have domain overlap and change the domain IDs for each of those switches.
